3 Claims.

This invention relates to improvements in ventilated handles and moreparticularly to ventilated hand grips for golf clubs.

An object of the invention is to prevent the accumulation of excessiveperspiration on the hand grips of manual implements and the like.

Another object is to precondition such gripping surfaces to prevent thecausing of undue perspiration.

Another object is to cause the rapid evaporation of moisture from thegripping area to lower the temperature and aid the adjustment of thehand to the grip, and insure the proper frictional coefficient at themoment of applying muscular force to the grip.

Another object is to adhere to the conventional size, shape and feel ofa golf club in the application of this invention thereto.

Other objects and advantages will appear as the description progresses.

In this specification and the accompanying drawing the invention will bedisclosed in its preferred form. It is to be understood however that itis not limited to this form because it may be embodied in other formswithin the purview of the claims following the description.

In the one sheet of drawings:

Fig. 1 is an elevation of the shaft of a golf club having its hand gripportion constructed in accordance with this invention.

Fig. 2 is an enlarged detail of the same showing the upper end thereofin fragmentary longitudinal section.

Fig. 3 is a modified form of the invention as ap- 35 plied to toolhandles, showing a fragmentary longitudinal section of a hammer handle.

Fig. 4 is an end view of the same.

In detail the construction shown in the draw.- ing, referring first toFig. 2, comprises the conventional golf club steel shaft I. These shaftsare tubular and are tapered in graduated section to the lower end whichis fixed in the head 2 in the approved manner.

This invention consists primarily in the modification of the outer andlarger end of the shaft to accomplish the objects of the invention. Thehollow plug 3 is driven into the open end of the shaft I with the largerhead 4 protruding. The center hole 5 leaves the hollow shaft l open to-the atmosphere.

'Ihe handle portion of the shaft is provided with lateral perforations6. These are overlaid 55 by a porous layer l such as spiral strips ofwire mesh or other suitable material to permit free air circulationtherethrough.

The perforated leather strip 8 overlies and adheres to the similarlyperforated adhesive tape 9. The leather strip 8 and the tape 9 are woundspirally around the shaft end to complete the grip for the hand of theplayer. The adhesive tape 9 securely attaches the strip 8 to the layerl. The last wrapping is securely fixed to the head 4 at A and wound withtwine at its lower end at B.

This laminated form of porous or perforated material forming the gripportion of the handle permits free circulation of air between the atvmosphere and the hollow center of the tubular shaft I. `With ordinaryskill the present grip can be built up and still preserve the same feelas the conventional grip as applied to wooden or lsteel shafts.

When successfully played the game of golf requires a nicety of mentaland muscular coordination. In most players the concentrated demand uponthe nervous system is apt to cause undue sweating of the hands. 'Ihiscauses a slimy accumulation on the grip making it diflicult to obtainthe necessary friction for the purpose, without a muscular tension whichwill interfere with the free swing of the club so necessary indeveloping the maximum of skill.

In .applying this invention to wooden golf clubs or tool handles themodification shown in Fig. 4 is suggestive. VThe handle II! is reducedto form the shoulder portion II, and further reduced to form the stemI2. The tubular shell I3 of sheet steel, liber or the like is perforatedas at I4 and shaped to give the desired hand grip. The larger outer endis closed by the thimble I5, snugly fitting the stem I2 and flanged backupon itself and clinched within the end of the sleeve I3.

The perforations I6 in the thimble I5 provide for circulation of airtherethrough into the interior of the handle.

The sleeve I3 is enclosed within a layer composed of a strip ofperforated leather or the like cemented or otherwise fixed thereto.There is a free circulation of air through the perforations I4 and I 5around the stem I2.

The swing of the golf club and the tool handle assures the displacementof any air impounded in the interior of the respective grip portionsthereof. This displacement of air can be increased in the case of thesteel Shaft I, by an opening, as at I, through the body of the head 2,see Fig. 1.

Having thus described this invention, what ls I,

claimed and desired to secure by Letters Patent is:

l. A hollow perforated handle for implements; a layer of Wire meshoverlying said perforate handle; and a perforated grip portion enclosingsaid layer of Wire mesh.

Y 2. A tubular shaft for golf clubs having a perforated handle portion;a plug in the outer end of said shaft having a hole longitudinallytherelo through and a head of greater diameter than said shaft; areticulate layer wound upon said perforated handle portion of the shaft;a perforated adhesive tape overlying said reticulate layer; and
